“…The obtained results of the dependence of the lateral displacement and the angle of the transportation vehicle, and of the first and second masses on the time indicate that the natural oscillations of the masses of transportation vehicle and the masses, which are the sum of two harmonic oscillations, are non-damping [15] since while solving the problem we disregarded the action of the inelastic resisting forces of the dampers. Since the periods of oscillations of the transport vary little in 1 0.7 (sec) T  , z have the form of beatings.…”

“…The possibility of transition to a simplified system with two degrees of freedom makes it possible to obtain analytical calculations to estimate forced vibrations of a transportation vehicle. And reducing the system of differential equations, which describe the movement of engineering objects, to a single higher order equation sometimes makes it easier to obtain analytical solutions [13][14][15][16].…”

The article considers free and forced oscillations of a system with six degrees of freedom with symmetrical and asymmetrical mass-inertial characteristics. The conditions of single-frequency oscillations are obtained. Initial deviations and initial velocities must be interconnected through one of the amplitude distribution coefficients. The differential equations of free vibrations of the system in principal coordinates are six independent linear differential equations of second order. Their common solution is obtained. We examine the possibility of reduction in the quantity of degrees of freedom of the considered system from six to two ones. Passing from six degrees of freedom to two was substantiated with the aid of the numerical experiments. According to calculations, linear and angular deflections of the transportation vehicle, which has six and two degrees of freedom, differ not more than by 10%. This fact indicates that it is possible to replace a study of a system with six degrees of freedom with a system with two degrees of freedom. An example of the transport system, which has three degrees of freedom, is considered. The obtained differential equation is solved in the final form with the specific relationship of the parameters. Analogously, there are equations derived and solutions obtained for the systems, which have one, one-and-ahalf and two degrees of freedom. The equations obtained allow you to define transformations of right parts depending on the considered case of external influences applied to the system and on the number of degrees of freedom.

“…Charge materials are consumed for the main silicon reduction reaction to form silicon dioxide, which may be accompanied by a transition into carbon monoxide in parallel with the formation of intermediate silicon monoxide, as well as silicon carbide during overheating, especially at the start of the smelting process and during the primary arc [14]. A separate consumption item is the unresponsive carbon that is derived from charcoal, which forms nanoparticles in the form of amorphous carbon, active pure carbon, or fullerenes.…”

The aim of this paper is to define and select stable zones in the off-gas duct of an ore-thermal furnace using a mathematical model. This is needed to increase the effectiveness of exhaust gas composition control in metallurgical silicon production. Methods. The goals of this study were achieved by means of computational fluid dynamics. A model with a water-cooled furnace roof as well as a model comprising steel gas passes with a sliding shutter was developed using ANSYS Fluent software. Both models were symmetrical to ensure a uniform gas-dust distribution, which allowed us to test the adequacy of the obtained models. The models were based on the Navier–Stokes equations system as well as on a discrete phase model (DPM) that was developed using the Euler–Lagrange method. Results. As a result of the modelling, a transition flow mode (Re 0-7437) was revealed behind the sliding shutter. As such, it can be assumed that the most suitable place for measuring equipment to be installed is directly behind the closed part of the sliding shutter.
